The paper presents barrettes, which are a useful method of designing non-direct foundations of engineering construction. The methodology is based on the distribution of forces acting on a foundation capping slab into each barrette, which depends on its stiffness. To determine the proper stiffness of an individual barrette comprising the foundation system, the transformational function of a pile with large diameter was used. Finally, the stiffness of each barrette as an element of foundation system was corrected in view of the groupʼs impact.
